ASIO and Crossfading (1 Viewer)

[hwahrmann]

In the latest SVN (14625) i've added Crossfading support for ASIO Playback.

as i don't have native ASIO Hardware here, using ASIO4ALL, i would ask people with ASIO devices to test it and give me some feedback.

thx,

Helmut

I am also running ASIO4ALL and crossfading works fine thx: - I asked you if this was possible a while ago - you are a wizard!).

Found a few things though:
* Selecting another song makes sound "micro-pause" (or mute?) a few ms.
* Sound got full of noise after a while. This probably due to my poor onboard-audio (Realtek ALC655), so don't mind it if nobody else reports a problem.

My connections is as follows:

Realtek ALC655 ---coax---> Logitech Z-5500

I'm using the ASIO4ALL driver and Realtek HD Audio onboard soundcard.

My crossfade kind of works - there are 2 short pauses as the tracks fade into each other.

Thanks for your hard work

Well the secret is not to commit anything, if you don't know when to do it. ))

i have a minimum buffer of 500ms, can't go below that.
And that is still played.
However with Fade In/out on Stop you shouldn't notice it.
Or do you have set that?

Hm, probably as you said an issue with your hardware. Don't have that and others didn't report it as well.


thanks for testing anyweay.

I'll check the Pause issue, altough i didn't notice it.
Maybe it's a combination of different parms.

Id just like to add to this thread, I have noticed since installing the stapshot with asio crossfading it has totally screwed up my ASIO output - sound quality has gone down the drain with a horrible buzzing noise. And this is with crossfading disabled. I re-installed the snapshot just before this and all is back to normal.

Same here too. I'm getting regular glitches and there is a terrible mess inbetween tracks. I don't even want crossfading!

ok guys,
i'll put together a test program with both methods available.
i'll post it here, when ready and ask you to run a test and tell me the result.
i'll try to gather as much information as possible to see what's happening.

hopefully we can fix it.
i have some idea, what might cause your problems, but i need to be sure, before changing too much within mp

kenwonders, parody and others having troubles with the ASIO Support.

Please unzip the attached file to a directory of your choice and execute BassAsioMixer.exe.

1. Select a Directory containing at least 2 mp3 or ogg songs. Only those 2 format work.
2. Select an ASIO Device
3. Press the "Start 1" button and let play 2 songs.
4. Press the "Stop" Button
5. Now Press the "Start 2" button and let play 2 songs.

You don't need to wait for the second song to finish, just let it play 10 seconds or so.
There is a Default Cross Fading of 4 seconds set.

Post the file output.txt, which is created in the program directory and let me know, how the 2 sample sound like.

thx,

Helmut

Greetings Helmut, I have just performed the tasks, and found 2 different but incorrect results.

'Start 1' reproduces the problem in Mediaportal for me. A click/pop every second or two, increasing with song detail.

'Start 2' is playing way too slow, something like 1/8th of the speed.
